Abstract

PURPOSE: To keep the teperature of the running water at comfortable levels at all times by detecting load variation in one direction (temperature rise direction) in a control system having an integrating element and shifting the charge on the integrating capacitor to the optimum value using a timer operated by this variation.
CONSTITUTION: The potential D in the potential divider formed by a temperature sensor 7, made up of a temperature sensing resistor with negative temperature coefficient, which detects the outlet temperature of hot water in a heat exchanger and a resistor 10 is compared with a reference voltage E by an operational amplifier 12. This potential difference is amplified and inverted and is then input into the transistor Tr13 which controls a proportional control value 5 in a gas supply pipe. Such a control circuit is provided with an operational amplifier 19 whose input is the variation in the potential D in the sensor 7. The output of the amplifier 19 is inverted when this variation exceeds the specified value. Its output is input into an operational amplifier 23 whose output is input into the operational amplifier 41 and is composed with the output of a supply water temperature sensor 37 and a Tr45 is controlled by the output of the amplifier 41.
